Total correction of tetralogy of Fallot following palliation

Fifty three patients with Tetralogy of Fallot were totally corrected following palliation. Intracardiac repair was not adversely influenced by a Blalock Taussig shunt or a Waterston shunt which did not produce kinking of the RPA. The results were less satisfactory after correction following a Potts shunt or a Waterston shunt with kinking at the site of the anastomosis.
